Application July 16, 1942, Serial No. 451,158

3 Claims.

The desk lamp of the present invention is designed to embody a combinedstandard and lamp socket which is formed of a section of tubingconfigured by the method set forth and described in the Dewey patent,No. 2,265,723, issued December 9, 1941.

The Dewey method is one which permits a continuous length of tubing tobe configured into unit sections of the desired form to constitute lampstandards and to be thereafter cut into units and employed in the mannerhereinafter set forth.

The standard of the present invention is so formed that its lower end isadapted to be socketed within a base mounting while its upper end is sofabricated as to provide socket connection for the bulb socket and atthe same time to afford a mounting for the bracket which carries thelamp shade.

Further objects and details will appear from a description of theinvention in conjunction with the accompanying drawing, wherein:

Figure 1 is a sectional elevation of a lamp embodying the features ofthe present invention;

Fig. 2 is a fragmental view partly in section showing the upper portionof the standard on an enlarged scale;

Fig. 3 is a cross sectional view taken on line 3--3 of Fig. 2 looking inthe direction of the arrows, and;

Fig. 4 is a cross section taken on line 4-4 of Fig. 2 lookin in thedirection of the arrows.

The combined standard and socket member ID is formed from an integralsection of tubing to provide a foot portion H at the lower end and asocket portion 12 at the upper end. The body of the standard in the formshown is given a combined tapered and undulatory configuration of anysuitable ornamental character. The socket portion I2 is provided nearits upper margin with a ring of protuberant lips l3 each of which is outfree along its lower edge [4 and pressed inwardly to expose the edge [5of the socket wall which thus affords a line of exposed stops l4 alongthe row of lips.

Below the ring of lips thus formed, the metal of the socket wall onopposite sides is out free along the edges [6 and outwardly pressed orofset away from the wall to aiford pockets I! for the reception of thelower ends of the arms l8 of an arch-shaped bracket 19 which supports adome-shaped shade 29. Each of the arms at its lower end is apertured toreceive a rivet 21 which is entered through an aperture 22 in theassociated pocket.

The ring of lips IS with the underlying stop edges 14 affords a snapsocket connection for a standard bulb socket 23 which is provided nearits lower end with a ring of outwardly protruding spaced lips 25presenting their free stop edges upwardly to engage with the downwardlypre sentedstop edges 14 on the lips I3 and, in order to guide the lips13, the metal surrounding-each of the lips 25 is depressed inwardly toafford guide channels 26 to hold the coacting lips in register while thebulb socket is being fitted and until the stop edges have snapped intointerlocking engagement with one another.

The lower or foot end ll of th standard is mounted within a socket wellformed in the center of a convexely rounded base 26a. The socket well isformed to provide cylindrical side walls 2! connecting with a base orfloor 28 with spaced apertures 29 formed in the corners where the sidewalls connect with the floor. Th lower end of the standard foot restsupon or near the floor 28 and has the metal adjacent the cornerapertures outwardly bulged or offset in the form of protruding bosses 30which extend through the corner apertures and serve to tightly interlockthe standard within the well in the base.

Th lamp constructed in the manner above described is one which consistsof a minimum number of parts which are secured together without the useof extraneous means of attachment save in the case of the rivets 2!which connect the said bracket to the standard. The standard itself canbe configured as a unit section and thereafter requires no furtherfabrication except in the formation of the lips l3 and the pockets I!which together with th protuberant bosses 30 constitute the onlyadditional displacement of the metal required. The method of forming thestandard permits an infinite number of variations in design and in thecombination of tapers and curvatures employed but without in any wayinterfering with or complicating the end portions of the standard, whichafford the connections heretofore described.

I claim:

1. In a lamp,.the combination of a tubular standard having at its upperend a socket portion adapted to receive a bulb socket, the socketportion being formed to provide a plurality of inwardly protruding lipsout free along their lower edges to expose the wall of the socketportion and thus afford a plurality of stops, a, bulb socket providedwith a plurality of outstanding lips adapted to register with the lipsfirst described and to abut against the stop edges and a. bas providedwith a socket well adapted to receive the lower end of the standard,said socket well having a surrounding side wall and floor with aperturesformed at the corner junction between the wall and the floor, and thefoot of the standard being provided with outwardly offset bosses enteredthrough said apertures to interlock the parts together.

2. In a lamp, the combination of a tubular standard having at its upperend a socket portion adapted to receiv a bulb socket, the socket portionbeing formed to-provide a plurality of inwardly protruding lips out freealong their lower edges to expose the wall of the socket portion andthus afford a plurality of stops, a bulb socket provided with aplurality of outstanding lips adapted to register with the lips firstdescribed and to abut against the stop edges, and a base I formed ofsheet material bulged upwardly in its center and therein provided with asocket well formed by inwardly depressing the material and adapted toreceive the lower end of the standard, said socket well having asurrounding side wall and floor with apertures formed at the cornerjunction between the wall and the floor, and the foot of the standardbeing provided with outwardly offset bosses entered through saidapertures to interlock the parts together.

3. In a lamp, the combination of a tubular standard having at its upperend a socket portion adapted to receive a bulb socket, the socketportion being formed to provide a plurality of inwardly protruding lipsout free along their lower edges to expose the wall of the socketportion and thus afford a plurality of stops and further provided withspaced upwardly opening pockets formed by offsetting the walls of thestandard below the lips, a bulb socket provided with a plurality ofoutstanding lips adapted to register with the lips first described andto abut against the stop edges, a lamp bracket comprising arms havingtheir lower ends entered into said pockets,

and a shade carried thereby, and a base formed of sheet material bulgedupwardly in its center and therein provided with a socket well formed byinwardly depressing the material and adapted to CLARENCE L. DEWEY.
